The AEM X-Series 30-0301 digital pressure gauge provides high-speed accuracy for monitoring oil, fuel, or air pressure from 0 to 100 PSI (0 to 7 BAR). Featuring a slim 0.825-inch overall depth and a shallow 0.200-inch cup, this 52mm (2-1/16 inch) gauge can be surface-mounted or installed in shallow pods where traditional mechanical or electronic gauges won't fit.

Built for advanced data integration, the 30-0301 includes AEMnet CAN-bus connectivity for daisy-chaining with the Infinity ECU, Series 2 EMS, or AQ-1 Data Logger. It also provides a 0-5V analog output for compatibility with third-party engine management systems and loggers. The interface features a programmable center LED display that is 87% larger than previous AEM generations, paired with 24 green outer LEDs for a sweeping needle effect.

• Range: 0-100 PSI / 0-7 BAR (User-selectable units)
• Form Factor: 52mm (2-1/16") diameter; ultra-slim 0.825" mounting depth
• Data Interface: AEMnet CAN-bus enabled and 0-5V analog output
• Features: Peak/Recall buttons, user-selectable threshold warnings, and auto-dimming sensor
• Construction: Positive locking connectors for secure electrical contact
• Part Number: 30-0301

Personalize the appearance of your AEM Performance Electronics 30-0300 X-Series Wideband UEGO AFR Gauge with this genuine Silver Bezel and White Faceplate Accessory Kit. Designed to allow for seamless integration with varied interior aesthetics or existing gauge clusters, this kit provides a high-contrast alternative to the standard black finish.

This accessory kit includes a precision-molded silver bezel and a dual-faced white faceplate featuring both Air/Fuel Ratio (AFR) and Lambda scales. Engineered for a direct fit on the slim 52mm X-Series gauge housing, these components maintain full access to the interface buttons and do not interfere with the auto-dimming feature or the digital center display.

• Specifically designed for AEM X-Series Wideband UEGO AFR Controller Gauge (PN 30-0300)
• Includes one silver replacement bezel for 52mm gauge housings
• Includes one white dual-faced faceplate (AFR and Lambda scales)
• Direct replacement for original black bezel and faceplate components
• Maintains factory-level fit and finish
• Manufacturer Part Number: 30-0300-ACC

The AEM X-Series Wideband UEGO AFR Controller Gauge (30-0300) utilizes patented X-Digital technology (Patent 9,575,030) to deliver the fastest response times for more accurate engine tuning. By minimizing deadtime—the delay between exhaust gas changes and sensor reporting—this controller provides the high-speed feedback necessary for safe, precise fuel mapping in high cylinder pressure applications and EFI systems.

• Superior Response: Independently tested as the fastest responding wideband controller among 17 competitors for improved feedback control.
• Comprehensive Connectivity: Features 0-5V and RS232 outputs for data logging, plus AEMnet (CANbus) for daisy-chaining up to 16 cylinders.
• Precision Display: User-configurable 3- or 4-digit display can toggle between AFR, Lambda, and O2% readings with an auto-dimming feature.
• Simplified Calibration: Factory-calibrated resistor eliminates the need for free-air calibration, though the option is supported for advanced users.
• Smart Detection: Built-in auto-sensor detection for both AEM FAE and Bosch LSU 4.9 wideband sensors.
• Low-Profile Fitment: Standard 52mm gauge diameter with a slim 0.825-inch total depth and a shallow 0.200-inch cup depth.
• Complete Package: Includes black bezel and black double-sided faceplate; compatible with supply voltages up to 16V.
